A 41-year-old woman and her 15-year-old daughter drowned at West Mersea beach in Essex on Wednesday evening while attempting to rescue a seven-year-old boy, police have confirmed. The child remains in a critical condition in hospital following the incident near Colchester.

The victims, identified by a family member as Shally Rahman and her daughter Samiha Rahman, were on a holiday trip to the coast when the tragedy occurred. All individuals involved in the incident knew each other, according to Essex Police.

Detective Chief Inspector Al Pitcher stated that initial investigations suggest the mother and daughter entered the water in an effort to help the boy who had gotten into difficulties. Police are appealing for witnesses and have been speaking to dozens of individuals to establish the full circumstances surrounding the event.

The incident has had a profound impact on the local community, with residents describing the scene as "horrific." Bystanders, including teenagers working at a nearby cafe and an off-duty paramedic, rushed to the water to assist before emergency services arrived.

Matiur Rahman, Shally's brother-in-law, expressed the family's shock and grief, describing Shally as a "very helpful person" and Samiha as "very, very good." He explained that the family was enjoying a seaside holiday when a large wave reportedly contributed to the incident.

Emergency services, including the East of England Ambulance Service, HM Coastguard, and the RNLI, were praised for their swift and professional response. Despite their "best efforts," the mother and daughter could not be resuscitated. Four other individuals were taken to hospital following the incident.

Local councillor Carl Powling highlighted the rapid response of the Coastguard and RNLI. His daughter, Leonie Powling, who works at the Seaview Beach Diner, was among the young people who provided assistance at the scene, attempting to find equipment to reach those in the water.

Residents have laid flowers at the beach in tribute to the victims. The investigation by Essex Police is ongoing, with officers urging anyone with further information to come forward.
